EDGE BINDER AND METHOD OF PRODUCING THE SAME Application filed September 16, 1921.

To all whom it may concern:

Be it known that I, MARSHALL B. LLOYD,

a citizen of the United States, and a resident of Menominee, county of Menominee, and State of Michigan, have invented a certain new, useful, and Improved Edge Binder and Method of Producing the Same, of which the following is a specification.

My invention relates generally to methods and means for binding the strands forming an edge of a fabric, but relates more particularly to the binding of woven reed fabric and the like.

The general object of my invention is to provide a method of binding or securing the edge of such a fabric in a simple, quick and easy manner. It is also an object of my invention to provide an edge binder and method which shall securely lock the strands against displacement and in such manner that it will withstand great pulling or tensional forces.

I aim also to provide end edge binder and a method of applying the same whereby the binder strip shall be wrapped by or within the strands which it secures.

My invention consists generally in an edge binder, and method of application thereof, whereby the above named objects, together with others that will appear hereinafter, are attainable; and my invention will be more readily understood by reference to the accompanying drawings, which illustrate what I consider, at the present time, to

be the preferred embodiment thereof.

Insaid drawings:

Fig. 1 is a face View of a piece of Woven reed or like fabric, the edges of which are to be bound.

Fig. 2 is a face View of a metal strip used for the binder.

Fig. 3 illustrates one step in the process of preparing the metal strip for application to the fabric.

Fig. 4: shows the metal strip of Fig. 3 in position in the fabric, preparatory to the interlocking operation.

Fig. 5 shows a further step in forming the interlock.

Fig. 6 is a view of a piece of fabric completely locked; and

Fig. 7 is an enlarged sectional view substantially on the line 77 of Fig. 6.

which filler strands 2 are woven.

Serial No. 501,210.

The fabric here'shown is typical of woven reed fabric and the like and embodies therein a plurality of stakes 1, over and under Under methods of manufacture devised by applicant and heretofore patented, it is now the practice to weave the reed fabric and the like independent of the frame, of which it is to form a part, and thereafter to attach it to the frame. In order that the fabric may be manipulated without danger of the stakes or strands becoming loose or displaced, and also as an aid in applying the fabric to the frame it is necessary, or at least highly desirable, to bind or secure the ends of the filler strands.

Sheet metal, such as brass or steel, is generally employed for this purpose. The texture of metal and that of the reed fabric is quite difierent and when the metal is placed around the strands, i. e. the strands placed within a channel of metal, the metal is completely exposed to view and detracts from the appearance of the fabric. Reed fabric,

especially if it is the natural reed, is somewhat brittle and special care must be taken to prevent the sharp edges of the metal engaging and cutting the fabric. At the same time, it is necessary firmly to bind the edge of the fabric since it is often used in articles tensioning of the strands occur, and such as would withdraw them unless very tightly held.

I have devised an edge binder and a method of applying the same, which tenaciously holds the strands in place; which presents no sharp edges such as can injure the fabric and which, at the same time, is partially hidden from view, thus removing the objection that inheres in a metallically bound fabric of reed and the like when the edge binder is completely disclosed to view.

Having provided the woven reed or like fabric, asv shown in Fig. 1, I neXt provide a strip or ribbon of metal of the proper length, as shown in Fig. 2. As a next step, the ribbon of metal 3 is pressed or shaped to the form shown in Fig. 3, i. e. substantially V-shaped, having a curved bottom portion 3. Alternate filler strands 2 are bent'in opposite directions from the central plane of the fabric and the metallic member in the form shown in Fig. 3 is inserted as indicated in Fig. 4. In order to prevent the dis tortion of the V-shaped metal member and particularly to maintain the round bottom portion thereof, 1 temporarily insert a metal rod 4: which remains in place during the subsequent forming operations and is there after removed.

Having thus positioned the parts, as shown in Fig. 4-, as a next step the V-shaped metal and the contiguous filler strands are bent partially inward, as indicated by the dotted line portion in Fig. 4:. As a matter of convenience in performing these operations, the fabric is usually clamped in place, as by means of a screw clamp 5 illustrated in Fig. 5. As a next operation a die 6 forces the end portions of the V-shaped metal strip and the encompassing filler strands downwardly to the position shown in Fig. 5, lateral displacement of the parts being limited by the spacing bars Tand, 8 respectively. The die 6 is then removed and the temporary rod 4 withdrawn, after which side pressure is applied to compact or close the parts to the form shown in Figs. 6 and 7. By referring to Figs. 6 and 7, it will be observed that the respective liller strands pass completely around the outerportions of the metal binder and then pass. downwardly between those portions of the metal binder strip that were initially inwardly formed. It should, furthermore, be observed that all edge portions of the metallic binder that contact the filler strands are curved o1 rounded, thus obviating any danger of cutting or injuring the strands.

Any pulling or tensioning forces that are applied to the strands do not directly tend to pull the strands from their position within the binder. strip, since they are first snubbed by the wrapping thereof around the curved portions, before referred to. The result is that a strong, light, and extremely durable fabric is provided which can be manipulated and used without danger of disintegration.

Again since the strands pass over the outer surface of the metallic binder the continuous smooth or flat appearance thereof is destroyed and an appearance better adapted to harmonize with the fabric is produced.

The many advantages of this construction will occur to those skilled in this art, without further comment.

I claim:

l. The method of binding the edges of reed fabric and the like that consists in providing a strip of binding material substantially V-shaped in cross-section, in separating the strands to be bound, placing the V-shaped strip between the separated strands, and forming thestrands and the upper portions of the l-shaped binder strip inwardly.

esser i reed fabric and the like that consists in providing a strip of binding material substantially V-shaped in cross-section, but with a curved bottom portion, in separating the strands to be bound, placing the V- shaped strip between the separated strands, and'forming the strands and the upper portions of the V-shaped binder strip inwardly.

l. The method of binding the edges of reed fabric and the like that consists in providing a strip of binding material, substantially V-shaped in cross-section, in separating the strandsto be bound, placing the V-shaped strip between the separated strands, and forming the strands and the upper portions of the \I-shaped binder strip inwardly, the folds in the binder strip being formed to curved shape.

9. The method of binding the edges of reed fabric and the like that consists in providing a metal strip of binding material substantially V-shaped in cross-section, but with a curved bottom portion, in separating the strands to be bound, placing the V- shaped strip between the separated strands, placing a rod in the bottom of the V-shaped binder strip, and forming the strand and the upper portion of the V-shaped binder strip inwardly.

10.
